CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 784,837, dated March14, 1905.

Application filed November 7,1904. Serial No. 231,659.

To all whom it may concern.-

Be it known that I, EDWARD CLIFF, a citizen of the United States, and aresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Car-Trucks,of which the following is a specification.

The invention relates to improvements in car-trucks, and pertains moreparticularly to the bolsters and means for connecting the ends of sameto the side frames of the truck; and the said invention consists in thenovel features and combinations of parts hereinafter described, andparticularly pointed out in the claims.

The object of the invention is to improve the truck as a whole and toprovide a highlyeflicient truck-bolster with means for securing the endsof the same to the side frames in such manner that the latter may notshift laterally from the bolster or even become loose due to the effectof curving, one object of the invention being to preserve the squarenessof the truck and secure the many benefits consequent to that condition.

The nature and objects of the invention will be fully understood fromthe detailed description hereinafter presented, reference being had tothe accompanying drawings, in which Figure 1 is a top view, partlybroken away, of a truck constructed in accordance with and embodying theinvention. Fig. 2 is a transverse section of same on the dotted line 2 2of Fig. 1. Fig. 3 is a side elevation of same, the wheels, axle-boxes,and like parts being omitted. Fig. d is a vertical section on the dottedline 4 4 of Fig. 2. Fig. 5 is a bottom view of a portion of thebody-bolster with the side-bearing rub-iron in position thereon. Fig. 6is an edge view of same. Fig. 7 is a detached perspective view of oneend portion of the bolster. Fig. 8 is a sectional view of same on thedotted line 8 8 of Fig. 7, and Fig. 9 is a top view of same.

In the drawings, 10 designates the sideframe of the truck, and in thepresent instance this frame is of the usual diamond type, comprising anupper arch-bar 11, alower arch-bar 12,

and a tie-bar 13, these bars being of wellknown form and construction.

The bolster is designated by the numeral 1 1 and is in one integralcasting, having heads at its ends adapted to engage and be secured bythe column-bolts 16 to the side frames 10. The bolster 1 1 comprises thebottom 17, sides 18, and transverse partitions 19, which connect saidsides and are integral with the bottom 17. The partitions 19 subdividethe bolster into a series of compartments 20, 21, and 22, all of whichare normally open at their upper ends, by reason of which the bolster inrespect of said compartments may be easily cast and withdrawn from thesand, thereby avoiding in respect of the said compartments coring andlike operations. The compartment 21 is rectangular in outline and has araised seat 23 surrounding the opening 2A for the king-bolt, and uponthis seat 23 are placed the four coiled springs 25, upon which is placedthe cap 26, whose upper surface afl'ords the center-bearing 27 and whosesides are of rectangular box-like form and guide within the verticalwalls of the compartment 21, the said sides being extended downwardlyalong the outer sides of the springs and being normally free of saidwalls.

The compartments 20 are adjacent to the side frames 10, and they alsoare rectangularin outline and formed with seats 28 to receive the setsof coiled springs 29, there being four springs in each of thecompartments 20, corresponding with the springs in the compartment 21.Upon the sets of springs 29 are placed the caps 30, whose sides are ofbox-like form and extend downwardly along the outer sides of the springs29 and guide within but are normally free of the vertical walls of thecompartments 20. Upon the upper ends of the caps 30 are formed thesegmental raised side bearings 31, which cooperate with the rub-irons82, carried by the body-bolster 33, these rub-irons 32 being ofsegmental outline adapted to the side bearings 31 and having at theiropposite edges the downwardly-extending segmental flanges 3A to passdownwardly upon the opposite edges of the side bearings 31, as shown inFig. 2, so as to preserve the proper relation of said side bearings andrubirons to each other. During the swiveling action of the body-bolster33 the rub-irons will move upon the arc of a circle upon the sidebearings 31, but will be prevented by the flanges 34: from movinglaterally off of said side bearings.

The compartments 22 are also of rectangular outline and are open attheir upper ends, and they are provided with openings 35 in their bottomfor the escape of dust and water.

The heads are wider than the main body of the bolster, and they extendfrom the ends of the bolster proper between the upper and lowerarch-bars 11 12, the said heads 15 at their opposite side edges (lookingat the side of the truck) being cored out for lightness, as shown by thedotted lines in Fig. 3 and solid lines in Fig. 2, and affording theupper and lower horizontal sections 36, in contact with the upper andlower arch-bars 11 12 and adapted to receive the column-bolts 16, whichpass through said sections 36 and also through the bars 11 12 13 of theside frames. The opposite side portions or columns of the heads 15(looking at the side of the track) are designated by the numeral 37, andthese portions 37 are only open at their outer ends, being closed attheir inner and upper and lower ends and outer and inner sides, and thesaid portions 37 are connected at their outer and inner sides with eachother by the webs 38 39 and outwardly-extending section 40 of thebolster, the section 10 being about on a level with the bottom of theends of the bolster and being integral with the webs 38 39. The webs 3839 below the sections 40 are arched, as shown in Figs. 2 and 3, and thesaid webs above the said sections 420 are recessed or concave, as at 4112, Fig. 2, these recesses extending downwardly from the upper arch-bar11 and the recess 12 being deeper than the recess 41. The sides of thecaps 30 adjacent to the recesses 12 are also recessed, as at 13, andthese recesses 11 12 13 are provided to enable the convenient inspectionfrom the outer side of the side frames of the springs 29 below said caps30. Below the springs 29 the seat 28 therefor contains vertical openings14 (indicated by dotted lines in Fig. 2,) and these openings,whilepermitting water and dust to escape, also admit of the introduction ofatorch up through them when it is desired to inspect the springs 29through the openings or recesses 41 42 13. The torch may be introducedto the compartment through the arched opening at the lower portion ofthe webs 38 39 while at the same time the inspector is observing thesprings 29 through the aforesaid openings 11 42 13. The portions orcolumns 37 are inte gral with the webs 38 and 39 and with the body ofthe bolster, the body of the bolster and the heads 15 on the endsthereof being one integral casting. The portions or columnposts 37 ofthe heads 15 have upon their upper and lower ends the gibs or flanges45, which engage the opposite side edges of the arch-bars 11 12 andprevent any lateral movement of the bolster or any shifting of the sideframes therefrom.

The bolster is preferably cast with suitable lugs 46 for thebrake-hangers.

In the drawings the springs 29 are shown as being under the pressure ofthe car-body and its load, and the purpose is to cause each of the setsof springs to take about one-third of the load at each truck in lieu oflocating the load on the center plate. The caps 26 somewhat loosely litthe compartments 21 20, so as to allow sufficient lateral thrust whennecessary, and I deem it of special advantage that the said caps andcompartments are of rectangular outline and that the springs 25 29 areof about equal strength and arranged in rectangular sets and to takeabout equally the car-body and its load.

The bolster above described is adapted for application to any of theusual diamond trucks, and it will be observed that the heads on the endsof the bolster strengthen the side frames, that the truck-frame is heldrigid and square by the bolster and its heads, and that the column-boltssecure the side frames, bolster, and heads together.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a ear-truck, the side frames having upper and lower bars, thebolster having on its ends the heads extending between said bars, andmeans rigidly securing said heads to said bars, said bolster beingformed with the vertical compartments at its center and adjacent to itsends, combined with the springs seated in said compartments, and thecaps mounted on said springs and affording the center and side bearingseats, said springs and caps being arranged to receive the car-body andits load about equally; substantially as set forth.

2. In a car-truck, the side frames having upper and lower bars, combinedwith the integral cast bolster having on its ends the heads adapt-ed tosaid bars and affording columnposts through which the column-bolts pass,said posts having on their upper and lower ends the gibs or flangesextending on opposite sides of said bars; substantially as set forth.

3.
